LED drivers and power converters cover a wide range of applications from lighting to displays to mobile devices. In the first half of this session, multiple efficient LED drivers are presented. Two approaches for 5-output Single-Input Multiple-Output DC-DC converters, using adaptive energy recovery and a combined switched capacitor with absolute inductor current emulation techniques, are presented. For LED lamps, a cost-effective and novel primary-side regulation method is disclosed. The second half of the session addresses evolving areas for efficient power converters; a wide range high-conversion-ratio switched-capacitor converter, a very-high-voltage Silicon Carbide JFET switching driver and inductive power transmission techniques.
